anyways, it looks like you could use a layer mask for this. the characters are on one layer and the pattern on the one above. add a layer mask to the pattern layer. then do a gradient from black to white or black to transparent on a new layer. copy the gradient and paste it into the mask.

Create a transparent layer and set your background color to the desired color (I picked a yellow).
Go to Filters > Distorts > Mosaic and set the highlighted ones below (you can experiment with the others, but make sure you set the highlighted ones):

Duplicate the mosaic pattern, and run the mosaic filter one more time, but this go-around, set the Tile Spacing to a little bit higher (I used 3.0). Click OK.

Run Gaussian Blur on this new layer and adjust the blend mode, if desired. Merge both layers together. Here's my result:

Now, try experimenting with the Perspective Tool to get the angle you want. Here's a screenshot of mine:
